1. If you previously used all speakers through wireless connection mode, you need to re-install all speakers.

2. If you previously connected a speaker with a cable and added the other speakers, connect one of the speakers in use with a cable and switch on other speakers for automatic network connection.

If automatic network connection is not activated even after waiting for more than 1 minute, reset and re-install the speakers according to the instructions of Music Flow Player application. If it keeps failing, turn off and on again the speaker connected by the cable, and try again.
